ROUTINE MAINTENANCE
Before performing maintenance, unplug the oven. During cleaning, use protective gloves, mask and garments as required by
standards.
At the end of each workday clean the inside of the oven with appropriate convection ovens following the suggestions of your
supplier. Do not use corrosive or acidic convection ovens, or convection ovens which are not suitable for this type of cleaning.
To make cleaning easier, remove the lateral diffusers by lifting them slightly so they are free of the holding pegs.
Clean the stainless steel parts daily with lukewarm soapy water, and rinse thoroughly. Then dry.
Absolutely do not clean the stainless steel with steel wool or common steel brushes, since they may leave ferrous particles which
may oxidize, thus causing rust spots.
Stainless steel wool can be used in the direction of the satin finish.
If the oven is not used for long periods, use a cotton ball to lay a coat of petroleum jelly on all surfaces; also regularly ventilate the
rooms.
OVEN CHAMBER CLEANING
! Remove any food and/or fat residues from the oven chamber after each cooking cycle.
! The combination of fat, heat and forced circulation dirties the oven. Only by cleaning the oven daily is it possible to avoid
difficult cleaning operations.
! To clean the oven, use a suitable de-greasing convection oven (non-foaming) as suggested by your detergent retailer. A
spray is preferable to reach behind the protection shield. Do not use abrasive or corrosive substances, scrapers or steel
wool (fig.12).

! Adhere to safety instructions included with cleaning convection
ovens for the protection of skin and eyes. When cleaning,
proceed as follows:
a) Heat the oven chamber to approx.158-176°F and clean it
using the de-greasing detergent in the recommended
quantities.
b) Close the oven and heat it.
c) Let the cleansing convection oven act for 20-30 minutes and
then turn the oven off.
d) Slowly open the oven with care to avoid eye and skin
damage.
e) Remove the racks or pans from the oven, remove the rack supports attached to the side and shield, remove the
shield by loosening the fastening screws. Wash separately (they can also be placed in the dishwasher).
f) Clean and rinse the oven and fan with water.
g) Re-install the shield and the rack supports.
h) Dry the oven by turning the CONVECTION cycle on.
To make cleaning the oven chamber easier, it is possible to remove the door completely in a few simple steps as shown in figures
13A & 13B. Follow the sequence in reverse order to re-install the door.
